Title: Improvements to the apparatuses for applying elastomeric fillers to tire bead cores.
IPC: B29C67/00
Filed: 1980-10-09
Abstract: Apparatus for automatically applying elastomeric fillers (R) to tire bead cores (C) comprising one or more drums (3, 4, 5) for holding the bead core on which the filler is applied when the drum rotates around its axis. The apparatus is provided with means (14) which stretch the filler when it is dragged into rotation with the bead core on the drum so as to produce a stiffening effect which opposes bendings of the filler and therefore maintains the filler substantially in a position in alignment with the drum midline. The apparatus is further provided with means (21) for discharging the bead core/filler assembly in a plane unchanged with respect to that determined by the stretching means in order to permit the collection of the various filler/bead core assemblies the one after the other.

Title: Process for the production as asymmetric hydantoins.
IPC: C07D491/107
Filed: 1985-08-20
Abstract: An improved process for preparing (4S)-6-fluoro-spiro-[chroman-4,4 min -imidazolidine]-2 min ,5 min -dione (sorbinil) or its (2R)-methyl derivative (2-methylsorbinil) is disclosed herein, starting from p-fluorophenol in each instance. The final products obtained have known pharmaceutical value as agents for the control of certain chronic diabetic complications. Key steps concerned with the process involve converting p-fluorophenol into the appropriate beta -(4-fluorophenoxy)-alkane halide, followed by amidoalkylation with N-benzoyl or N-(lower alkanoyl)- alpha -hydroxyglycine to form an intermediate 2-amidoalkylated derivative thereof, and then dehydration and spiroalkylation of said intermediate by treatment with a dehydrating agent and a base to yield a spiroalkylated azlactone compound. The latter compound is then subsequently converted to the known 4-amino-6-fluorochroman-4-carboxylic acid or the novel (2R-methyl derivative thereof, both in the form of their hydrohalide acid addition salts, by employing acid hydrolysis and the intermediate spiro-amino acid hydrohalide salt is thereafter converted to the corresponding methyl or ethyl ester and resolved with alpha -chymotrypsin to afford the desired (S)-methyl or (S)-ethyl ester. Treatment of either of these latter two esters with an alkali metal cyanate in an acid medium then effects conversion of same to the desired spiro-hydantoin ring compound. Alternatively, the spiro-amino acid hydrohalide salt can also be converted to the desired spiro-hydantoin ring compound in a known manner, involving a sequence of three reaction steps. The spiroalkylated azlactone compound of the instant invention, as well as the methyl and ethyl esters mentioned above, are themselves novel compounds and are valuable as synthetic intermediates in the process of this invention.
